Foldable canopy

ABSTRACT

A retractable canopy having a fixed support coupled to a movable boom, an actuator to move the movable boom from a first position proximate a first end of a fixed support to a second position proximate a second end of the fixed support, at least one link coupled to the fixed support and the movable boom, at least one strut rotatably and translatably coupled to the at least one link, and a cover coupled to the fixed support and the movable boom to be deployed from a storage configuration to a deployed configuration by movement of the movable boom.

TECHNICAL FIELD

The present disclosure pertains to deployable coverings for objects and, more particularly, to canopy devices, systems, and methods, that enable selectable degrees of deployment and provide a fully folded configuration useful with vehicles and in connection with boat lifts.

BACKGROUND Description of the Related Art

Canopies for objects, such as vehicles, are known. Typical canopies include a frame and a cover to provide a protected space under which to store an object or park a vehicle. The canopy frame typically extends vertically and horizontally to span an area such that when an object is placed under the canopy, the cover provides protection for the object from the sun, rain, or snow, among other environmental conditions. However, fixed or permanent canopies suffer from a number of drawbacks or disadvantages.

For example, the permanent shade created by fixed canopies is frowned upon in many jurisdictions because of the negative impact to surrounding ecosystems. Further, permanent canopies are not aesthetically pleasing and are typically viewed negatively by homeowners or neighbors. These problems are exacerbated when fixed canopies block waterfront views, or other scenic landscape views. Moreover, designing canopy covers and frames to handle snow and wind loads requires use of expensive and bulky parts, which increases cost for the consumer. Because fixed canopies are suspended above an area, most fixed canopies also do not provide adequate protection against environmental conditions impinging on the object or vehicle underneath the canopy from different angles, such as from the side. Such canopies are also not adjustable, meaning that the area covered by the canopy is fixed based on the size and arrangement of the frame, which limits use applications.

Some of the above issues are alleviated with removable canopy covers, but such canopy covers are typically formed from heavy material and are burdensome or cumbersome for the owner to manipulate on and off of the frame. Other solutions include covers that extend laterally toward the support surface to provide protection to the sides of an object under the canopy, but such solutions do not address the environmental or aesthetic concerns mentioned above and are also not adjustable. As such, current canopies suffer from a number of disadvantages, as do available proposed solutions.

DETAILED DESCRIPTION

The present disclosure is generally directed to foldable or retractable canopies with a movable boom relative to a fixed boom, and an actuator for manipulating the movable boom between a storage configuration and a deployed configuration. The following description will proceed with respect to a specific implementation of a foldable canopy for a watercraft lift. However, it is to be appreciated that the devices, systems, methods, and concepts presented herein can be applied to canopies for other types of vehicles as well and, as such, the present disclosure is not limited to retractable canopies for watercraft lifts.

FIGS. 1A-1D depict operation of a first implementation of a support structure for a retractable canopy of the present disclosure as used in connection with an example boat lift system. A canopy member, typically a flexible sheet of weather resistant flexible material, is supported by the support structure over the boat when the support structure is fully open. When the support structure is fully retracted, the canopy member is folded.

More specifically, FIGS. 1A-1D are perspective views of an implementation of a retractable canopy 20 for a watercraft lift 22. The retractable canopy 20 includes a fixed boom 24 extending from the watercraft lift 22. A movable boom 26 is supported on the watercraft lift 22 to enable rotational movement of the movable boom 26 relative to the watercraft lift 22. An actuator 28 (shown in FIG. 1C) is operatively connected to the watercraft lift 22 and the movable boom 26 to rotate the movable boom 26 between a first position shown in FIG. 1A and a second position shown in FIG. 1B. In the first position shown in FIG. 1A, the movable boom 26 is spaced from the fixed boom 24. In the second position, the movable boom 26 is adjacent to the fixed boom 24.

The retractable canopy 20 further includes at least one first linkage 30 extending between the fixed boom 24 and the movable boom 26 and at least one second linkage 32 extending between the fixed boom 24 and the movable boom 26. At least one first strut 34 is rotatably supported by the at least one first linkage 30 and slidably supported by the at least one second linkage 32, as further described herein. In one implementation, the retractable canopy 20 includes at least one second strut 36 rotatable relative to the fixed boom 24 and at least one third strut 38 supported by the movable boom 26. A cover 40 is secured at a first end 42 to the fixed boom 24 and at a second end 44 to the movable boom 26.

When the movable boom 26 is in the first position, the cover 40 is supported in an extended configuration above a watercraft area (e.g. area of boat 46) by the fixed boom 24, the movable boom 26, the at least one first strut 34, the at least one second strut 36, and the at least one third strut 38 as shown in FIG. 1A. When the movable boom 26 is in the second position, the cover 40 is supported in a retracted configuration adjacent to the fixed boom 24, the movable boom 26, the at least one first strut 34, the at least one second strut 36, and the at least one third strut 38, as shown in FIG. 1D.

In one implementation, the retractable canopy 20 further includes a support post 48 coupled to the watercraft lift 22. When the movable boom 26 is in the first position, the movable boom 26 contacts the support post 48, as best shown in FIG. 1A. Further, the retractable canopy 20 includes a support rod 50 coupled between one of the at least one third struts 38 and one of the at least one first linkages 30. Preferably, the at least one first strut 34 is also rotatably supported by the at least one second linkage 32. In yet a further implementation, each of the at least one first linkage 30 and each of the at least one second linkage 30 include a first portion 52 coupled to the fixed boom 24 and structured to rotate relative to the fixed boom 24 and a second portion 54 coupled to the movable boom 26 and structured to rotate relative to the movable boom, the first portion 52 coupled to the second portion 54, wherein the first portion 52 and the second portion 54 are structured to rotate relative to each other.

FIGS. 2A-2C illustrate a second implementation of a folding canopy system 100 in various stages of deployment. FIG. 2A illustrates the canopy system 100 in a folded or storage configuration, FIG. 2B illustrates the canopy system 100 in a partially or semi-deployed configuration, and FIG. 2C illustrates the canopy system 100 in a fully deployed configuration.

With reference to FIGS. 2A-2C, the canopy system 100 is coupled to a watercraft lift 102. The watercraft lift 102 includes fixed supports 104, which may be referred to herein as supports, support rails, a support frame, or a support assembly. In the illustrated implementations, the canopy system 100 is coupled to the fixed supports 104 of the watercraft lift 102. In this implementation, there are two fixed supports 104 on opposite sides of the watercraft lift 102. However, in other implementations, the fixed supports 104 may be a single fixed support 104, such as a support frame that is part of the watercraft lift 102. The fixed supports 104 each include a first end 106 and a second end 108 opposite the first end 106. In one implementation, the first end 106 is a forward or front end and the second end 108 is an aft or rear end.

As shown more clearly in FIGS. 2B and 2C, the canopy system 100 includes a fixed boom 110 coupled to the fixed supports 104 at the first end 106 of the fixed supports 104. The fixed boom 110 may, in some implementations, be referred to as part of the fixed support 104. In other words, the fixed support 104 includes the fixed supports 104 and the fixed boom 110. The fixed boom 110 may be coupled to the fixed supports 104 with bolts, nuts, screws, brackets, or other fasteners. In an implementation, the fixed supports 104 are hollow longitudinal members and the first ends of the fixed boom 110 are sized and shaped to be received inside of the fixed supports 104 to be secured in place by nut and bolt assemblies using through-holes in the fixed boom 110 and the fixed supports 104 at the first end 106 of the fixed supports 104. A second end of the fixed boom 110 is spaced from the first end by a length of the fixed boom 110.

The system 100 further includes a movable boom 112 coupled to the fixed supports 104. In the storage configuration shown in FIG. 2A, the movable boom 112 is proximate to the fixed boom 110 and the first end 106 of each of the fixed supports 104. However, as the movable boom 112 is deployed from the storage configuration to the deployed configuration in FIG. 2C, the movable boom 112 becomes spaced from the fixed boom 110. In FIG. 2C, the movable boom 112 is positioned proximate the second end 108 of the fixed supports 104. The movable boom 112 is manipulated between the storage configuration and the deployed configuration by one or more actuators 114. In the illustrated implementation, there are two actuators 114, one for each side of the movable boom 112. However, in other implementations, the movable boom 112 can be manipulated using only a single actuator 114 or with more than two actuators 114. The actuators 114 are coupled to a respective fixed support 104 and the movable boom 112. Each of the actuators are configured to rotate the movable boom 112 from a first position (e.g., the storage configuration) proximate the first end 106 of each of the fixed supports 104 to a second position (e.g., the deployed configuration) proximate the second end 108 of each of the fixed supports 104.

FIGS. 3A-3C illustrate side views of the canopy system 100 in the storage configuration, the partially deployed configuration, and the deployed configuration, respectively. With reference to FIGS. 2A-2C and 3A-3C, the system 100 further includes a first link 116 coupled to the fixed boom 110 and the movable boom 112 as well as a second link 118 coupled to the fixed boom 110 and the movable boom 112. The first and second links 116, 118 are structured to rotate relative to the fixed boom 110 and the movable boom 112. The first link 116 is spaced from the second link 118, with the first link 116 being an upper link and the second link 118 being a lower link relative to the fixed boom 110, in one non-limiting example. In one implementation, the system 100 includes only a single link, such as either one of first or second link 116, 118. In yet further implementations, there are more than two links 116, 118, such as three, four, or more links.

A plurality of first struts 120 are coupled to the first link 116 and the second link 118, wherein each of the plurality of first struts 120 are translatable relative to the first and second links 116, 118, as described below with reference to FIGS. 6A-6C. Further, each of the plurality of first links 120 are structured to rotate relative to the first link 116 and the second link 118. In the illustrated implementation, there are four struts 120 in the plurality of first struts 120, however, in other implementations, there are more or less than four struts 120, such as one strut 120 up to ten or more struts 120. Each of the first struts 120 are coupled to the first link 116 and the second link 118 at different points along the first link 116 and the second link 118, respectively. As such, each of the connections between the first struts 120 and the links 116, 118 are spaced along the links 116, 118. However, in other implementations, the first struts 120 may share common connection points on the first link 116 and the second link 118.

The system 100 further includes a plurality of second struts 122 coupled to the movable boom 112 and structured to rotate relative to the movable boom 112. In the illustrated implementation, the plurality of second struts 122 includes three struts 122, while in other implementations, the plurality of second struts 122 includes more or less than three struts, such as only one strut, or more than five struts. The plurality of second struts 122 are coupled to the movable boom 112 at three distinct connection points spaced along the movable boom 112, as described with reference to FIG. 8. However, in other implementations, the plurality of second struts 122 are coupled to the movable boom 112 at a single connection point.

A plurality of third struts 124 are coupled to the fixed boom 110. The plurality of third struts 124 includes four total struts in the illustrated implementation, although in other implementations, the plurality of third struts 124 includes more or less than four struts. Each of the plurality of third struts 124 are coupled to the same connection point on the fixed boom 110. In other implementations, each of the plurality of third struts 124 are coupled to the fixed boom 110 at different points, similar to the plurality of second struts 122. Only three of the third struts 124 are rotatable with respect to the fixed boom 110, in one implementation. Specifically, the plurality of third struts 124 includes a strut 124 a that is fixed relative to the fixed boom 110 and struts 124 b, 124 c, and 124 d that are coupled to the fixed boom 110 and structured to rotate relative to the fixed boom 110. As shown in FIGS. 3A-3C, all of the struts 120, 122, 124 are structured to be positioned proximate one another when the movable boom 112 is in the storage configuration proximate the fixed boom (FIG. 3A), and they are further structured to be spaced from one another when the movable boom 112 is in the extended or deployed configuration (FIG. 3C).

The system 100 further includes a support rod 126 coupled to one of the plurality of second struts 122 and the first link 116. The support rod 126 is coupled to a forward-most one of the plurality of second struts 122, which is the second strut 122 closest to the first end 106 of the fixed supports 104 of the plurality of second struts 122. The support rod 126 is coupled to the first link 116 and the strut 122 and structured to rotate relative to the first link 116 and the strut 122 so as to accommodate rotational motion of the first link 116 and the strut 122, in one implementation. In an alternative implementation, the support rod 126 is fixedly coupled to the first link 116 and the one of the second struts 122. In still further implementations, the support rod 126 is coupled to the second link 118 or the movable boom 112 instead of the first link 116.

A support frame assembly 128 is coupled to the movable boom 112. The support frame assembly 128 is structured to rotate from a position proximate the movable boom 112 when the movable boom 112 is in the first position (e.g., the storage configuration) as shown in FIG. 3A, to a position extended from the movable boom 112 when the movable boom 112 is in the second position (e.g., the extended or deployed configuration) shown in FIG. 3C. The support frame assembly 128 is shown more clearly in FIGS. 2B-2C and includes a frame 128 a coupled to the movable boom 112 and at least one support link 128 b coupled to both the movable boom 112 and the frame 128 a. The connection between the frame 128 a and the movable boom 112 is structured to enable rotation of the frame 128 a relative to the movable boom 112 and can include the frame 128 a coupled to the movable boom 112 with a pin or fastener through openings in the frame 128 a and the movable boom 112, as described herein. In an alternative implementation, the connection includes a bracket and pin or fastener assembly, similar to the type described below with reference to FIG. 5 and FIG. 8.

Similarly, the support link 128 b can be coupled to the frame 128 a to enable rotational motion of the support link 128 b relative to the frame 128 a and the movable boom 112. For example, the system 100 may include one or more brackets of the type described herein, wherein the brackets are coupled to the movable boom and the frame 128 a, and the support link 128 b is coupled to the brackets with pins or fasteners. In another implementation, the support link 128 b includes a hole with the frame 128 a inserted through the hole in the support link 128 b to enable rotational motion of the support link 128 b around the frame 128 a at one end of the support link 128 b.

When the movable boom 112 is in the first position, the support frame assembly 128 is structured to be positioned adjacent the movable boom 112 (see FIG. 2A). In other words, rotation of the movable boom 112 to the first position rotates the frame 128 a and the support link 128 b toward the movable boom 112 until the frame 128 a rests on the movable boom 112. When the movable boom 112 is in the second position, the frame 128 a and the support link 128 b rotate to extend from the movable boom 112 so as to cover an aft or rear end of a boat on the boat lift 102.

In particular, the frame 128 a and the support link 128 b extend from the movable boom 112 so that a cover coupled to the support frame assembly 128, such as cover 130 in FIG. 3C, is proximate to, and covers, a rear longitudinal edge 47 (see FIG. 1D) of a watercraft on the lift. The watercraft on the lift may be the boat 46 shown in FIG. 1D in one non-limiting example. Thus, the support frame assembly 128 extends the cover 130 (see FIG. 3B) described herein to provide protection for the aft or rear end of a boat on a boat lift, and in particular, the rear surface of a hull 49 (see FIG. 1D) of a watercraft on the watercraft lift 102 from sun exposure, wind, rain, and other external forces. In some implementations, the support frame assembly 128 and the cover 130 on the support frame assembly 128 are also proximate to and cover a swim platform or other structure coupled to the hull 49 at the rear longitudinal edge 47 (see FIG. 1D) of the watercraft.

The frame 128 a is coupled to the movable boom 112 at a location where the first link 116 is coupled to the movable boom 112, as shown in FIG. 3B. Further, the support frame assembly 128 includes only one support link 128 b coupled to the movable boom 112 and the frame 128 a at a center of the movable boom 112 and the frame 128 a in the illustrated implementation. However, in other implementations, the support frame assembly 128 includes multiple support links 128 b, with a position of each support link 128 b relative to the movable boom 112, the frame 128 a, and the other links 128 b selected according to design specification. For example, multiple support links 128 b may be evenly spaced relative to the movable boom 112 and the frame 128 a, or may be grouped together in close proximity toward a center of the movable boom 112 and the frame 128 a.

In one implementation, the frame 128 a is coupled to the movable boom 112 and structured to slide relative to the movable boom 112, such that a position of the frame 128 a can be adjusted to cover the remainder of the system 100 when the movable boom 112 is in the first (storage) position, as above. For example, the system 100 may include an actuator configured to translate the frame 128 a relative to the movable boom 112. Alternatively, ends of the frame 128 a are structured to be received in channels or guides in the movable boom 112, and the system 100 further includes a weight coupled to the frame 128 a to adjust a positon of the frame 128 a relative to the movable boom 112. Further, the system 100 may include springs in the movable boom 112 to slide the frame 128 a relative to the movable 112. Further, the system 100 may include the link 128 b replaced with a strap, wherein movement of the frame 128 a relative to the movable boom 112 is controlled with one of the above structures.

A cover 130 is attached to several components of the system 100 such that the cover 130 extends and retracts with the movable boom 112. The cover 130 is shown in FIGS. 3A-3C with dashed lines for clarity. The cover 130 may be comprised of flexible waterproof fabric or canvas, among other materials. In an implementation, the cover 130 is coupled to the strut 124 a of the plurality of third struts 124, which is fixed relative to the fixed boom 110. As such, the strut 124 a secures the cover 130 to the fixed boom 110 at a forward or front end of the system 100. At a rear end of the system 100, the cover 130 is secured to the support frame assembly 128. For example, the cover 130 may be secured to the support frame 128 a with stitching, or with fabric loops that extend from the cover 130, around the support frame assembly 128, and are secured to the cover 130 with stitching. In yet further implementations, the cover 130 is secured to the frame 128 a with hook and loops fasteners, or other fasteners.

In one implementation, the support frame assembly 128 is structured to rotate such that a portion of the cover 130 that extends from the movable boom 112 to the frame 128 a lays on top of the remainder of the cover 130 and the struts 120, 122, 124 when the movable boom 112 is in the storage configuration, as shown in FIG. 2A. The portion of the cover 130 corresponding to the support frame assembly 128 shields the remaining components of the system 100 from environmental conditions. Preferably, the portion of the cover 130 corresponding to the support frame assembly 128 (e.g., the portion of the cover 130 from the movable boom 112 to the frame 128 a) is comprised of a different material than the remainder of the cover 130. For example, the material for this portion may be vinyl, while the remainder of the cover 130 is waterproof canvas. Other materials are available for this portion of the cover 130 and can be selected according to design specification.

Further, the cover 130 is coupled to each of the plurality of first struts 120. For example, the cover 130 may include fabric loops that extend around the first struts 120 to be secured to the cover 130 with stitching, as above. The cover 130 extends from the storage configuration to the deployed configuration with the movable boom 112, with the coupling to the plurality of first struts 120 reducing sagging over the span of the cover 130 from the fixed boom 110 to the movable 112 in the deployed configuration. In the deployed configuration, the cover 130 has a length that is greater than a length of the boat lift 102 so as to protect a boat supported by the boat lift 102. Further, the support frame assembly 128 extends towards the water around a back of a boat on the boat lift 102, such that the cover 130 provides adequate protection from elements incident on the boat from all angles, including at the sides and the back of the boat.

In this implementation the cover 130 is similar to a tonneau cover in that the cover 130 covers all of the open passenger or cargo space of a boat parked on the boat lift 102. In the illustrated implementation, the cover 130 is not secured to the plurality of second struts 122, the plurality of third struts 124 b, 124 c, 124 d that are rotatable relative to the fixed boom 110, or the first and second links 116, 118. However, in an alternative implementation, the cover 130 is secured to each of the struts 122, 124, 124 c, 124 d, as well as at least one of, if not both of, the links 116, 118 to further prevent sagging of the cover 130.

In another alternative implementation, the cover 130 includes a strap coupled to the cover 130 on a side facing the system 100. The strap may be positioned centrally relative to the cover 130 and extending from the front to the back of the cover 130 relative to the system 100. The cover 130 may then be connected to the system 100 by coupling the strap to the struts 120, 122, 124, and the frame assembly 128, such as with hook and loops fasteners, or with fabric sewn to the strap. In yet further implementations, the system 100 may include multiple such straps coupled to the cover 130, which are located along the cover 130 and spaced from each other between sides of the cover 130 to prevent sagging of the cover 130 in the deployed configuration.

The system 100 further includes a support post 132 coupled to the fixed support 104 on each side of the system 100. Each support post 132 extends from the fixed support 104 perpendicular to the fixed support 104 and contacts the movable boom 112 when the movable boom 112 is in the second, or deployed position. A height and thickness of the support post 132 relative to the fixed support 104 can be selected according to design specification. In one implementation, the support post 132 is structured to limit rotation of the movable boom 112 such that the struts 120, 122, 124 do not contact and damage a boat on the boat lift 102, or the support frame assembly 128 does not extend to contact and damage a swim platform of a boat on the boat lift 102. In other words, when the movable boom 112 is in the second or deployed position, the movable boom 112 contacts the support post 132 to prevent further rotation of the movable boom 112 towards the fixed supports 104.

In one implementation, there is only one support post 132 in the system 100, which can be located on either side of the boat lift 102. In a further implementation, the system 100 does not include the support post 132. Rather, the system 100 includes only the actuator 114, wherein the actuator 114 is configured to provide sufficient resistive force to hold the movable boom 112 in the deployed configuration without the support post 132. However, it is to be appreciated that including the support post 132 allows for selection of a smaller, cheaper actuator 114. Further, the support post 132 aids in increasing the service life of the system 100 because the support post 132 reduces tension on the actuator 114 when the movable boom 112 is in the deployed configuration. Reduction in the tension on the actuator 114 reduces the likelihood of damage or failure of the actuator 114 over time.

As shown more clearly in FIGS. 2A-2C, the system 100 includes supports 134 coupled to the boat lift 102 and the fixed boom 110 to support the fixed boom 110 in an extended relationship relative to the fixed supports 104. The supports 134 are optional with a size, shape, and length that can be selected according to design specifications for the system 100. Further, the system 100 includes a frame 136 coupled to and extending from the fixed boom 110 at a front end of the system 100. An opening 138 extends through the frame 136 between the frame 136 and the fixed boom 110. A wire lattice 140 is disposed in the opening 138 and coupled to the fixed boom 110 and the frame 136. As shown in FIG. 2A, the frame 136 and the wire lattice 140 are structured to receive the struts 120, 122, 124 and the cover 130 when the movable boom 112 is in the first position. The wire lattice 140 includes a plurality of openings 142 (see FIG. 2B) extending through the wire lattice 140 in order to allow for air circulation to dry the cover 130 when the cover 130 is received on the wire lattice 140. Further, the plurality of openings 142 (see FIG. 2B) reduce the amount of shade produced by the system 100 when the movable boom 112 is in the deployed configuration, as light is able to pass through openings 142 to the surrounding environment. Reduction in permanent shade reduces the environmental impact of the system 100.

Instead of the wire lattice 140, the system 100 can include various other structures in the opening between the frame 136 and the fixed boom 110. For example, the system 100 may include metal wires, metal posts or rods, wood, netting, or other types of mesh structures that are coupled to the fixed boom 110 and the frame 136 and that allow for air circulation. In other implementations, the system 100 includes materials that do not include a mesh or openings 142. Rather, the system 100 includes solid materials such as vinyl or plexiglass, which may be clear to reduce permanent shade, or other materials. As such, the structure or material in the opening between the frame 136 and the fixed boom 110 can be selected according to design specification.

Turning to FIGS. 4A-4C, the system 100 includes the actuator 114 coupled to the fixed support 104 and the movable boom 112. The actuator 114 is preferably an electric linear actuator. As such, the actuator 114 is configured to be connected to an external power supply, which provides voltage to drive the actuator 114 in response to a user activating the actuator 114 through a remote switch. In an alternative implementation, the actuator 114 is a hydraulic actuator configured to be connected to a hydraulic fluid system activated by a remote switch to drive the actuator 114. The actuator 114 is coupled at a first end 114 a to the fixed support 104 with a first bracket 142 having flanges 142 a, 142 b, and a hole 142 c extending through the flanges 142 a, 142 b.

The first end 114 a of the actuator 114 includes a pair of arms 144 coupled to and extending from the actuator 114 with apertures extending through the arms 144 structured to align with the holes 142 c through the flanges 142 a, 142 b of the first bracket 142. The hole 142 c and the apertures in the arms 144 are sized and shaped to receive a fastener, such that the actuator 114 is rotatable relative to the first bracket 142 and the fixed support 104 about the fastener. In an alternative implementation, the actuator 114 is fixed to the first bracket 142 by a fastener through the hole 142 c and the apertures of the arms 144 to prevent rotational motion of the actuator 114 relative to the first bracket 142. The support post 132 is coupled to the fixed support 104 with the first bracket 142, as shown in FIGS. 4A-4C. However, in an alternative implementation, the support post 132 is coupled to the fixed support 104 at any location along the respective fixed support 104, such as in front of the actuator 114 or spaced from the actuator 114 toward the second end 108 of the fixed support 104.

The actuator 114 includes a second end 114 b coupled to a first lever arm 146. The first lever arm 146 is coupled to second end 114 b of the actuator 114 and a second bracket 148 fixed to the fixed support 104. The second bracket 148 includes a first pair of flanges 148 a, 148 b and a hole 148 c through the first flanges 148 a, 148 b sized and shaped for receiving a fastener. The hole 146 c and a hole in the first lever arm 146 are structured to receive a fastener or pin, such that the first lever arm 146 rotates relative to the bracket 148 and the fixed support 104. A second lever arm 150 is coupled to the movable boom 112 and the first lever arm 146. A hole 150 a extends through the second lever arm 150 to align with a corresponding hole through the movable boom 112, wherein the hole 150 a and the hole of the movable boom 112 are structured to receive a pin or fastener to enable rotation of the second lever arm 150 relative to the movable boom 112.

The second lever arm 150 is coupled to the first lever arm 146 in a similar manner. The movable boom 112 is coupled to a second pair of flanges 152 a, 152 b of the second bracket 148 by a pin or fastener extending through a hole 152 c through the flanges 152 a, 152 b and a hole in the movable boom 112. In one implementation, the actuator 114 includes only a single post at each end 114 a, 114 b of the actuator 114 rather than a pair of arms. The single post at each end 114 a, 114 b of the actuator 114 may be coupled to the bracket 142 and the first lever arm 146 in a similar manner to above. In yet further implementations, the bracket 142 may include only a single flange instead of flanges 142 a, 142 b. Moreover, the actuator 114 may be coupled to the fixed support 104 and the first lever arm 146 by any other connection that enables rotational motion of the first lever arm 146 relative to the actuator 114 and that enables rotation of the actuator 114 relative to the fixed support 104.

In operation, the user activates a switch (not shown) configured to provide power to the actuator 114 to manipulate the actuator 114 from an extended position shown in FIG. 4A to a retracted position shown in FIG. 4C. The extended position of the actuator 114 corresponds to the movable boom 112 being in the first or storage position and the retracted position of the actuator 114 corresponds to the movable boom 112 being in the extended or deployed configuration. Retraction of the actuator 114 rotates the first lever arm 146 towards the fixed support 104, which in turn rotates the second lever arm 150 towards the fixed support as well. Rotation of the second lever arm 150 results in rotation of the movable boom 112 towards the fixed support 104.

In one implementation, a control system 143 (FIG. 4A) is connected to the actuator 114 to control the actuator. The control system 143 may be connected to the actuator 114 through a wired connection 145. In one implementation where the actuator 114 is an electric linear actuator, the control system 143 is connected to an external power supply and selectively provides power to operate the actuator 114 through wire 145. In other implementations where the actuator 114 is a hydraulic actuator, the control system 143 is connected to a hydraulic fluid system and is configured to control the actuator 114 based on an input of the user. For example, the control system 143 may be mounted on the fixed support 104 and electrically connected to the actuator 114. The control system 143 may include a toggle switch to be manipulated by the user. Manipulation of the toggle switch in one direction (such as up, down, left, or right) corresponds to extension of the actuator 114 towards the position shown in FIG. 4A. Conversely, manipulating the switch in the opposite direction corresponds to retracting the actuator 114 towards the position shown in FIG. 4C.

In yet a further implementation, the control system 143 includes hardware, such as a receiver or transceiver connected to a microprocessor, configured to communicate with a remote control containing similar hardware. For example, the remote control may include buttons corresponding to extension or retraction of the actuator 114. When the user presses the button to extend the actuator 114, the remote control converts the user input to a signal that is transmitted by the hardware of the remote control to the hardware of the control system 143. The hardware of the control system 143 then provides power (or hydraulic fluid) to the actuator 114 to operate the actuator 114. The signals sent by the remote control to the control system 143 can be transmitted using various communication protocols, such as infrared, radio frequency, Bluetooth®, or Wi-Fi®.

The user can select an amount of rotation of the movable boom 112 relative to the fixed boom 110. In other words, the user can selectively rotate the movable boom 112, via the control system 143, to any position between the first position and the second position described herein. For example, the user may select to extend the actuator from the retracted position in FIG. 4C a small amount (e.g. less than the amount shown in FIG. 4B, or less than halfway) in order to raise the movable boom 112 enough to drive a boat off the boat lift 102, without manipulating the movable boom 112 all the way to the first or storage position. The length of each of the first and second lever arms 146, 150 as well as an orientation of a coupling between the first and second lever arms 146, 150 can be selected to vary a torque or force on the movable boom 112 in different applications.

FIG. 4C further illustrates the movable boom 112 contacting the support post 132 to limit rotation of the movable boom 112 to prevent damage to the boat on the boat lift 102.

FIG. 5 illustrates a connection between the plurality of third struts 124 and the fixed boom 110. The strut 124 a is fixed to the fixed boom 110 by a bracket 154. As shown in FIG. 5, the strut 124 a is disposed on the fixed boom 110 over at least a portion of a length of the strut 124 a. The strut 124 b is coupled to the bracket 154 by a pin or fastener structured to be received through hole 156 in a connector 158 structured to receive the strut 124 b. In one implementation, the strut 124 b is coupled to the bracket 154 on a first or front side of the bracket 154 while the struts 124 c, 124 d are coupled to the bracket 154 on a second or rear side of the bracket 154. Each of the struts 124 c, 124 d are structured to be received in connectors 158 coupled to the bracket 154 by a pin or fastener structured to be received through a hole 160 through the bracket 154 to enable rotation of the connectors 158 relative to the bracket 154.

FIGS. 6A-C illustrate the plurality of first struts 120 in additional detail. Each of the plurality of first struts 120 are coupled to the first link 116 and the second link 118 by a plurality of first connectors 162 and a plurality of second connectors 164, respectively. The plurality of first connectors 162 are coupled to the first link 116 and structured to rotate relative to the first link 116 and the plurality of second connectors 164 are coupled to the second link 118 and structured to rotate relative to the second link 118. Each of the plurality of first struts 120 includes a first portion 120 a that is fixed to a respective one of the first connectors 162. The plurality of second connectors 164 are structured to receive a second portion 120 b of each of the plurality of first struts 120 in a telescoping or sliding arrangement. In other words, the second connectors 164 are preferably hollow tubes sized and shape to receive the second portion 120 b of each first strut 120 such that the second portion of each strut 120 can translate with respect to the second connectors 164.

For example, as the movable boom 112 (FIGS. 2A-2C) moves from the first position towards the second position, each of the first struts 120 rotate with the connectors 162, 164. The second portion 120 b of each first strut 120 translates relative to the respective one of the second connectors 164 until the first connector 162 contacts a corresponding second connector 164 to prevent further translation, as shown in more detail in FIG. 6B and FIG. 6C. In other words, when the movable boom 112 is in the first position, the first struts 120 are in a retracted configuration relative to the second connectors 164. In response to the movable boom 112 rotating towards the second position, the second portion 120 b of each first strut 120 slides relative to the second connectors 164 to extend from a respective second connector 164, as shown in FIG. 6A and FIG. 6B. The translation of the second portion 120 b of each first strut 120 is limited by the first connector 162 contacting the second connector 164 in the fully extended position, which may improve the stiffness of the system 100 with the connectors 162, 164 acting as truss elements. In one implementation, when the movable boom 112 is in the fully deployed configuration, the first connector 162 does not contact the second connector 164, but rather, the connectors 162, 164 are spaced from each other.

In an alternative implementation, the plurality of first struts 120 do not translate relative to the links 116, 118. In such an implementation, the system 100 does not include the struts 120 having first and second portions 120 a, 120 b, and the system 100 does not include connectors 162, 164. Rather, the system 100 includes the plurality of first struts 120 having a single, integral, unitary body coupled to the links 116, 118 with a structure to enable rotational motion. For example, the struts 120 may include holes through the struts 120 that align with corresponding holes through the links 116, 118 structured to receive a fastener.

Alternatively, the system 100 may have rotational joints or brackets of the types described herein attached to the struts 120 and the links 116, 118. Still further, the system 100 may include the struts 120 coupled to the first link 116 and the second link 118 with the struts 120 structured to rotate relative to the links 116, 118. Instead of the struts 120 translating relative to the second link 118, a control or swing arm is attached to an end of each strut 120 and the second link 118. The control arm is structured to move a respective strut 120 in an arc relative to the links 116, 118.

FIG. 7 illustrates the first link 116 and the second link 118 in additional detail. The first link 116 includes a first arm 116 a coupled to the fixed boom 110 and a second arm 116 b coupled to the movable boom 112. The first arm 116 a and the second arm 116 b of the first link 116 are coupled together with a first hinge 165. The first hinge 165 includes a first plate 166 a coupled to the first arm 116 a and a second plate 166 b coupled to the second arm 116 b of the first link 116. First barrels 168 a are coupled to the first plate 166 a in spaced relationship to each other. A second barrel 168 b is coupled to the second plate 166 b and is structured to be received in the space between the first barrels 168 a. The barrels 168 a, 168 b include an opening 170 sized and shaped to receive a pin or fastener to enable rotational motion of the barrels 168 a, 168 b relative to each other. Rotation of the barrels 168 a, 168 b enables rotation of the arms 116 a, 116 b of the first link 116 relative to each other via the plates 166 a, 166 b coupled to respective ones of the arms 116 a, 116 b and the barrels 168 a, 168 b.

In the illustrated implementation, there are two first barrels 168 a coupled to the first plate 166 a and one second barrel 168 b coupled to the second plate 166 b. However, in other implementations, there may only be one first barrel 168 a and one second barrel 168 b, or two second barrels 168 b and one first barrel 168 a.

The second link 118 similarly includes first and second arms 118 a, 118 b coupled together with a second hinge 172. The first arm 118 a is coupled to the fixed boom 110 and the second arm 118 b is coupled to the movable boom 112. The second hinge 172 includes plates 174 a, 174 b coupled to corresponding ones of the arms 118 a, 118 b. However, the second hinge 172 includes only one first barrel 176 a coupled to the first plate 174 a and only one second barrel 176 b coupled to the second plate 174 b.

The barrels 176 a, 176 b include an opening 178 extending through the barrels 176 a, 176 b sized and shaped to receive a pin or other fastener to enable rotation of the barrels 176 a, 176 b and the arms 118 a, 118 b relative to each other, similar to hinge 165 above. The hinge 172 for the second link 118 includes less barrels than the hinge 165 for the first link 116. It is to be appreciated that the number, size, and arrangement of the barrels of each of the hinges 165, 172 can be selected according to design specification, such as an amount force produced by the actuator 114 to manipulate the movable boom 112, which may result in larger or smaller hinges 165, 172 being selected.

In one implementation, the first and second hinges 165, 172 may be replaced with any other structure that enables rotation motion between the arms 116 a, 116 b, 118 a, 118 b. For example, first hinge 165 may be removed and the arms 116 a, 116 b of the first link 116 may each include holes structured to receive a fastener to secure the arms 116 a, 116 b to each other to enable rotational motion. The second hinge 172 may also be removed, with the arms 118 a, 118 b of the second link 118 coupled together in a similar arrangement. Other implementations replace the hinges 165, 172 with rods, bars, or plates coupled to respective ones of the arms 116 a, 116 b, 118 a, 118 b with holes at the end of the rods, bars, or plates structured to receive a fastener.

In yet further implementations, the first link 116 and the second link 118 do not include separate arms, but rather, are a unitary assembly with a rotational or articulating joint at the location of the hinges 165, 172. In other implementations, the first link 116 and the second link 118 include separate arms, but the hinges 165, 172 are replaced with a joint. In an alternative implementation, the hinges 165, 172 are replaced with brackets of the type described herein that are coupled to respective ones of the arms 116 a, 116 b, 118 a, 118 b and structured to receive a fastener to enable rotational motion. As such, the connection between the arms 116 a, 116 b of the first link 116 and the arms 118 a, 118 b of the second link 118 can be selected according to design specification.

FIG. 8 illustrates the connection between the second plurality of struts 122 and the movable boom 112 as well as the connection between the support rod 126 and one of the plurality of second struts 122. As mentioned above, each of the plurality of second struts 122 are coupled to the movable boom 112 at different locations along the movable boom 112, in one implementation. For example, one of the second struts 122 is coupled to the movable boom 112 with a first bracket 178 a at a first location, a second one of the second struts 122 is coupled to the movable boom 112 with a second bracket 178 b at a second location, and a third one of the second struts 122 is coupled to the movable boom 112 with a third bracket 178 c at a third location, wherein the first, second, and third locations are spaced along the movable boom 112.

Each of the brackets 178 a, 178 b, 178 c is an “L” type bracket with a first portion coupled to the movable boom 112 and a second portion extending perpendicular to the first portion in the shape of an “L.” Holes 180 a, 180 b, 180 c extend through respective ones of the plurality of second struts 122 and are structured to align with corresponding holes through the brackets 178 a, 178 b, 178 c. The holes 180 a, 180 b, 180 c and the holes through the brackets 178 a, 178 b, 178 c are structured receive a pin or fastener to secure the second struts 122 to respective ones of the brackets 178 a, 178 b, 178 c and to enable rotational motion of the second struts 122 relative to the brackets 178 a, 178 b, 178 c and the movable boom 112. The support rod 126 is coupled to a forward-most one of the second struts 122 (e.g., the second strut 122 the farthest to the left in the orientation shown) with a bracket 182. In one implementation, the bracket 182 includes flanges and a hole extending through the flanges structured to receive a pin or fastener, as described herein, to enable rotational motion of the support rod 126 relative to the second strut 122. In other implementations, the bracket 182 fixes the support rod 126 to the one of the second plurality of struts 122.

FIG. 9 illustrates an example connection between components of the struts 120, 122, 124 described herein. Each of the struts 120, 122, 124 are structured as hoops or frames with a first arm or rod 184 a and a second arm or rod 184 b coupled together by a connector 186. The connector 186 includes a first portion 188 a, which may be a first tube having an axial bore structured to receive the first arm 184 a. The first arm 184 a may be secured in the axial bore of the first portion 188 a with a friction fit or an adhesive, for example. In other implementations, fasteners are used to secure the first arm 184 a to the first portion 188 a of the connector 186. The connector 186 further includes a second portion 188 b, which may be a second tube having similar qualities to the first tube. The second portion 188 b is sized and shaped to receive the second arm 184 b. In the illustrated implementation, the first portion 188 a and the second portion 188 b are part of a single, integral, unitary body of the connector 186. However, in other implementations, the first and second portions 188 a, 188 b may be separate pieces coupled together to form connector 186.

The first and second portions 188 a, 188 b are supported by a brace 190 coupled to each of the first and second portions 188 a, 188 b and extending between the first and second portions 188 a, 188 b. The brace 190 provides structural support to the connector 186 to prevent the first and second portions 188 a, 188 b from breaking at a corner 192 between the portions 188 a, 188 b during normal operation. In one implementation, the corner 192 is rounded so as to prevent damage to the cover 130 during repeated folding and unfolding operations. Further, each of the struts 120, 122, 124 may include a connector 186 on each side of the respective strut 120, 122, 124 such that the struts 120, 122, 124 are hoops that extend around the boat on the boat lift without contacting the boat. As such, each of the struts 120, 122, 124 may include three arms or rods joined together by two connectors 186 to form a “U” shape. However, only one connector 186 is described in detail with respect to FIG. 9 to avoid repetition. In yet a further implementation, each of the struts 120, 122, 124 are a single, unitary, integral piece without connectors 186.

Unless stated otherwise, it is to be appreciated that the material compositions of the components in the system 100 described herein can be selected according to design specification. For example, the features described herein may be metal (steel, stainless steel, or aluminum, among others) as well as plastic or PVC, among others. Hence, the present disclosure is not limited by the material composition of the features described herein.

In the foregoing description, certain specific details are set forth in order to provide a thorough understanding of various disclosed implementations. However, one skilled in the relevant art will recognize that the present disclosed implementations may be practiced without one or more of these specific details, or with other methods, components, materials, etc. In other instances, well-known structures or components, or both, that are associated with the environment of the present disclosure have not been shown or described in order to avoid unnecessarily obscuring descriptions of the implementations.

Unless the context requires otherwise, throughout the specification and claims that follow, the word “comprise” and variations thereof, such as “comprises” and “comprising,” are to be construed in an open inclusive sense, that is, as “including, but not limited to.” The foregoing applies equally to the words “including” and “having.”

Reference throughout this description to “one implementation” or “an implementation” means that a particular feature, structure, or characteristic described in connection with the implementation is included in at least one implementation. Thus, the appearance of the phrases “in one implementation” or “in an implementation” in various places throughout the specification are not necessarily all referring to the same implementation. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more implementations.

In general, in the following claims, the terms used should not be construed to limit the claims to the specific implementations disclosed in the specification and the claims, but should be construed to include all possible implementations along with the full scope of equivalents to which such claims are entitled. Accordingly, the claims are not limited by the disclosure.
